New paper: "Library of Identification Resources: a FAIR overview of taxonomic keys"

Biodiversity research is supported by an ever-increasing volume of citizen science observations, on platforms such as Waarneming.nl/Observation.org and iNaturalist.org. Taxonomic expertise is essential to sustain these platforms, but can be difficult to spread due to the decentralized nature of many citizen science projects. In our new scientific article in Biodiversity Data Journal we describe how and why to record information resources for the taxonomic identification of organisms in a FAIR database, and how to query that data to find applicable resources for an observation.

So I created the Library of Identification Resources (LoIR) which so far contains 2,158 records of such information resources, 54% of which are freely available online. At the moment, most resources are meant for groups of insects in parts of Northwestern Europe, but anyone can help by adding more resources!

See below for caption
Fig. 1: Geographical and taxonomic focus of the resources currently included in the Library of Identification Resources. (A) Choropleth of the geographic scopes of resources in the catalog. 460 publications with a geographic scope that cannot be expressed in administrative borders were omitted. (B) Breakdown of publications by the taxonomic group and continent. Publications spanning multiple continents and/or multiple taxonomic groups are counted for the category “Other”.

A major feature of the LoIR is a special search engine, where someone can enter an observation of an organism, for example a hoverfly in Nijmegen, The Netherlands, and it returns the most applicable resources for that observation. It works by comparing the list of expected species of hoverflies in The Netherlands to the different available resources. Try it out!

As the database and search engine grow, more and more citizen scientists should be able to find the resources needed to continue their extensive work.
